ABSTRACT
Field Assisted Sintering Technology (FAST) is a new sintering technique that is capable of sintering at much lower temperatures and much shorter times than conventional sintering. Flash Sintering
and Spark Plasma Sintering are two types of Field Assisted Sintering Technologies that are discussed in this review. These new sintering techniques are compared to conventional sintering techniques. Conventional sintering mechanisms are introduced and compared
to Spark Plasma Sintering and Flash Sintering mechanisms. Since Flash Sintering and Spark Plasma Sintering are relatively new technologies, there remain numerous unanswered questions about the processes. Although many mechanisms have been proposed for both
Flash Sintering and Spark Plasma Sintering, the underlying mechanisms behind these sintering techniques are still under debate. Some Flash Sintering mechanisms proposed in literature are discussed and compared. Future research directions are proposed and
could shed some light on the mechanisms involved.
